Changing logging level of com.atlassian package?

[jmox]

Hello,

I wonder what is the com.atlassian package in the logging and profiling Jira administration site AND what is the outcome of changing its logging level. Does anyone know?

I couldn't find anything about here:

https://confluence.atlassian.com/adminjiraserver/logging-and-profiling-938847671.html

Nor here:

https://docs.atlassian.com/software/jira/docs/api/7.2.1/overview-summary.html

And the last question: could com.atlassian package logging level be set to trace to debug an app installed or that has nothing to do with the APPs installed?

Many thanks.
